Function principle of the Stirling motor
The principle of the Stirling motor is very old…and very simple! Over 2000 years ago in ancient Egypt, the expansion of heated air was used to set temple doors in motion. The hot air engine patented in 1816 by Robert Stirling is based on a similar principle: A burner filled with fuel heats the air inside a cylinder and thereby purveys energy to the motor that activates through piecing of the flywheels.
Stirling motors are impressive machines despite their simple design!
The air in the closed operating cylinder is heated by the flame, expands, and flows past the expulsion piston to the other side of the cylinder, where it pushes the working piston towards the outside. Since the expulsion piston is now connected to the rotating flywheel it now moves back, letting the air behind the expulsion piston cool to create a vacuum. This vacuum ensures that the working piston gets sucked back. The process then repeats from the beginning and the machine works.
